The parts of a SaaS product that are expensive to retrofit are the parts nobody demos: tenant isolation, entitlements, billing state and the admin tooling your own team lives in.
The business problem
A single-tenant prototype gets sold to a second customer, and the tenancy model is now an emergency.
We design the boundary first - what a tenant is, what it owns, and what happens at every billing transition.
What we build
Isolation, data residency and per-tenant configuration.
Plans, limits and what actually happens when one is hit.
The console your team uses to answer a customer question.
Sign-up to first value, instrumented so you can see where it stalls.
Reference architecture
Boring on purpose: one API surface, one source of truth per concept, integrations at the edge, and an audit trail from day one. Diagrams are produced per project and included in the handover pack.
